I have a few ideas and suggestions id like to throw out for V7
One thing my users complain about is the lack of ability to upload their avatar directly. Right now I have them using the workaround of uploading the image in a post and then linking to the image for their avatar.
Also this may have been discussed elsewhere allready but I think polls should also be controlled by username as well as cookies and IP, this will make it more full proof and prevent any cheating.
Banning by username and disallowing certain usernames would also be great additions.
Lastly some sort of Database backup and restore utility in the admin control panel like that found in PHPbb would be really cool.
Even if none of these features are implemented, the board is great as is. Keep up the great work Borg!
